My invention relates to a easel type of loose-leaf binder and it relates. more particularly to a loose-leaf binder of a type adapted for use both new and useful as a loose-leaf book and also as an easel display stand for displaying the successlve leaves of the book. One of'the objects of my inventionis the provision of a loose-leaf binder of this character, which may be most effectively used for display purposes, of clearance for each page with the greatest amount as it is folded while the device is in the easel form.

With the above and other lowing detailed description,

objects in view which will appear more fully from the tol my invention consists of a loose-leaf binder including'a back, having spaced parallel hinge strips plates of substantially rigid character, to

each of which is hingedly s ecured a corresponding substantially rigid or 'stitlt cover and to the outermost or free the covers a base panel being also hingedly edge of one of secured, so that when the book is opened into an easel, said base cover may form the base of a triangular easel.

My invention. further consists of a pair of opposed parallel paper-clamp plates detachably secured to each otherby means of suitable posts, and confining between them a clamp plates being in turn hingedly secured to the hinged plates of the the base panel, opened to its easel tire bound edges of the out from between the back of the book and clear of book.

Figure 6 represents a fragmentary view of the hinge members of the book in the easel condition, illustrating the effect on the rela* tion between the bound edges and the hinged strips as the pages are folded back. v

The loose-leaf book of my present invention includes a back 7 consisting generally of the top and bottom hinge strips or members 8 and 9 repetitively, which are preferably still, rigio members covered on both sides with the outer and inner linings 10 and 11, which are then united at 12 to form a flexible connection between the top and bottom hinge strips 8 and 9. To the bottom hinge strip 9, a pair of similar hollow tubular and in ternally threaded screw-posts 13 are rigidly suitable anchorages 1 embedded in said 9 or extending therethrough and hinge strip covered by the outer lining 10. A tubular correspondin to the desired spacing between the rigid or stiff hinge members or strips 8 and 9. Corresponding screws 16 are ex tended through the 1 per hinge strip or nieniher 8 and threaded into the corresponding hollow tubular screw-posts 3.3, thereby to lock and secure the two hinge strips in fixed aced relation to each other.

To the top and bottom hinge strips or members 8 and 9, corresponding stiff covers 18 and 19 are flexibly or hingedly secured, by means of: the oute and inner linings 10 and 11 shown particularly in Figure 5, whereby said covers may be bent back upononwith respect to said hinge members 8 and 9 respectively, when it is desired to open the book for use as an easel. The lines of flexible or hinged connection are indicated at 20 and 21 respectively.

- plates or papcr-cla1np1ng To the outer edge 22, of the bottom cover 19, a relatively stiff base panel 23 is flexibly connected, also preferably by means of the inner and outer linings l0 and 1.1, which are joined to each other for a suitable distance indicated at 24, which distance is snaicient to bridge the thickness of the book when closed as indicated particularly in Figure l. The total width of the flexible stri a 24 formed by the union of the inner and outer linings, and the width of the base panel 23 are sulficient to form an appropriate base for the triangular easel shown particularly in Fig. ures 2 and 3. To the freeor. outer edge 25 of the base panel 23, a stiff flap or ab 26 is flexibly secured, also preferably by means of the inner and outer linings 10 and 11, which preferably extend the entire aggregate length of thesuccessive series of flexibly connected members 18, 8, 12, 9, 19,24, 23 and 26. The flap or tab 26 adapted to be folded up in overlapping relation to the lowermost or outer portion of the upper cover panel 18, when the latter is in the position shown in Figures 2 and 3. A pair of spaced snap-fastener sockets 2'7 are provided through the outermost portion of the cover 18, which are adapted to receive corresponding and registering snap-fastener studs 28 earned by the tab 26, when the device is set up as an easel, thereby detachably to secure said flap 26 to the cover member 18. When the device is closed inthe form indicated in Flgures 1, 4 and 5, the snap fastener sockets 27 recelve another pair of registering snap fastener'studs 29 whlch are secur d to or carr1ed by the base panel 23, thereby detachably to secure the upper cover 18 111 a closed condltlon. To the lower h1n e strip or member 9 the 1 7 11111 6 leaf 30 1s fixedl Y secured b rivets or r; a .g otherwise, and the outer edge 31 carries a plntle 32 extending longitudinally.

The stack of sheets 33 are perforated with as at 31t, forreceiving two or more apertures, binding posts.

A pair of opposed upper and lower binding plates or bars 35 and 36 areprovided, each being preferably formed of a strip of sheet-metal, the longitudinal edges of which are bent-in upon the strip so as to form a'strip or bar of approximately double thickness.

The edge 37 of the lower bar 36 is cut away at intervals, to enable it to serve as another hinge leaf, to coactwith the hinge leaf 30. The pintle 32 is thus extended through the front and cut-away edge 37 of the bar 36, so

that said bar is hingedly secured to the leaf 3,0, and hence to the'lower hinge member or strip 9. 1

A'pair of spaced tubular and internally threaded screw-posts 38 are rigidly secured to the lower bar 36, and at a right-angle thereto, by any suitable anchorage such as the strip Y flange 39 embedded or interposed )etwecn A corresponding :0 are sini- 41 embedded in or interposed between plies or layers of the upper bar Screws 42 are then extended upper bar 35 and threaded into i, and internally threaded posts ereb to clamp the paper 33 between the inipez' and lower bars 35 and respectively, as indicated in Figures 3, 41 and 5.

When the book is used as merely looscleaf book, the bool: is placed flat on the table and the upper cover 18 is folded back about the flap folding line 20, and the base panel 23, carrying the tab strip 26, are also folded out inv the opposite direction flat onto the table. The sheets or leaves 33 maythen be folded back one or more at a time in regular book fashion. i

WVhen the book is'used for-display purposes, the base panel 23 is bent back further and is joined to the cover 18 by means of the tab 26, as indicated particularly in Figures 2 and 3.\ When in this condition, the bars 35 and 36 are swung out from between the hinge members 8 and 9 forming iart of the back of. the book, as indicated particularly in Figures 2 and 3, this swinging action taking place about the pintle 32. As the successive leaves ofthe sheaf of pages 33 are folded backward, their weight and position operate on the bars 35 and 36 to swing them in a reverse direction, back into, the space between the hinge members Sand 9, thereby to tend to relieve the tension" on the sheaf of pages foldediback and to permit a freer motion of folding of each leaf, and to expose more freely to view the uncovered page of the front face of the easel, without any overhanging portion of the folded-back pages. By this means, the leaves or sheets 33 may be folded back with greater facility and the pages may Letters Patent, is
